ok guys i am using a A64 4600x2 on a gigabyte K8NXP SLI board (latest F11 Bios). i have *language!* kingston ram (pc3200). i have tried to O/C and when the memory was in single channel mode i could get an overclock of 2.81 (234x12) with Vcore @ 1.5 and DDR overvolt +0.2.

Now i have my memory in dual channel mode i cant get the machine to POST with anything over 218x12. If i use easytune i can get to 226x12. i have tried the ram divider @ various combinations. i haven't touched the DDR timings(coz i know nowt about them). i am using stock cooling but can upgrade to a ThermalRight XP120 if i need to.

does anyone have any suggestions. i am not looking for massive O/C (i would be happy with 2.8 - 3.0 Ghz). Am i looking for too much or should be happy with what i have managed to get?

cheers

In Single Channel mode the memory controller isn't working as hard as when in Dual Channel mode. Basically your memory controller seems to be flaking out at the higher clockspeed.

You could push the vCore a little higher but I wouldn't recommend that unless you have a good cooler and it might also kill your CPU - don't hold me accountable if your baby melts lol.

Also, you can't just expect a massive overclock. Some chips are better than others and on the face of it yours might not be that great.

2.6GHz is a nice overclock so I would be happy! However, you could try lowering the CPU multi to x11 or x10 or even lower and upping the FSB. My 4400+ would not POST at 2.6GHz with the CPU multi at x11 but I lowered it to x9 and increased the FSB - stable as a rock.

I sure weescott said that AMD X2's can take up to 1.65 volts.

But thats with DECENT Cooling,


I run my X2 4000 @ 1.5 volts @ 255 x 11 ( 2805 )


I'm going to try for 3ghz @ 1.6 Volts later :D
 
Well, I did mention the need for good cooling. 1.65 is probably fine with an AC Freezer 64 Pro or a Ninja. The stock cooler is probably about as much use as wafting a palm leaf at 1.65V lol

Temps wise I would reckon 1.65V would be way to much for any air cooler. My max load temps would exceed 60C using about 1.475V on an BT.
